Towards Privacy-Aware Mobile Device Sharing
4th International Workshop on Security and Privacy in Spontaneous Interaction and Mobile Phone Use (in Conjunction with Pervasive 2012), Newcastle, United Kingdom, June 2012 (bib)

Modern smartphones are loaded with sensitive data. At the same time, there are situations, in which a user must share or wants to share the device with others. Since common authentication methods still follow a single-sign-on approach, new privacy issues arise. We argue that sharing cannot always be avoided and thus should be supported by refined authentication systems. Our assumption is based on the findings of a focus group that we conducted to get insights about sharing practices, privacy threats and need for protection.
